5 State of Pennsylvania, have invented a cer- Terminal Seal for Storof which the following is a tain new and useful age Batteries, specification.

The principal object of the present invention is to provide for sealing the aper-.

ture in the cover through which the terminal post of the plate structure passes and the invention, generally state comprises wedge means arranged between and co-operating with the post and cover for holding in compression a gasket arranged on the post and interposed between the under face of the cover and a shoulder on the post. 1

In the drawings Figure 1, is a transverse sectional view of a terminal seal for storage batteries embodying features of the invention.

Fig. 2, is a top or plan view, partly in section, of the same.

Fig. 3, is a side view of the terminal post showing a section of the wedge means in occupies although parts with which it co-operates are not shown, and Fig. 4, is a perspective view of the wedge structure detache I g In the drawings 1, is an apertured cell or jar cover. 2, is a terminal post for a set of'battery plates and it passes through the.

and is formed with a shoulder 4, underneath thecover. 5, is a soft packing gasket interposed between .the shoulder 4 and the ,under face of the cover. 6, is a transverse wedge engaging the post and cover for holding the gasket under compression. The post 2, is provided with inclined lateral notches 7, sh

undercut at 8, Fig. 1, and the wedges are rovided for cooperation with the notches and cover 1, andthese wedges are shown as beveled at 9, and connected by a U-shaped yoke 10, Fig. 4., The object of under-cuttin the notches and beveling the wedges is to old the latter in towards the post.
